So I'm not too familiar with the pi, my extent of experience with it is powering it on and setting up ssh so I can remotely log a usb-serial cable. Working on a project for work to try to automate some things and my first hurdle is trying to figure out a way to be able to switch inputs for one output. I'm not sure if this is possible using the GPIO pins or not. I don't need the pi to touch the data coming in at all.
What I currently have; 3 different alarm panels right now, each panel has 2 wires (Tx and Rx) I have those data wires connected to a board and I have 1 radio, which I can then connect to the breadboard to connect to the desired panel. Pretty much I'm using the bread board to quickly switch between panels so I do not have to move the wires from one panel to the next everytime.
What I'm trying to do is use the pie to be able to electronically select which panel my radio is connected to. So the pi doesn't need to access the data at all.... just be able to select which panel.
